Four standard usage scenarios for the entire machine

1. Debugging of Web Console (Portable DAQ)

The browser directly connects to the default IP of the device, allowing for visual viewing of real-time waveforms and configuration of collection tasks without the need for programming, making it suitable for on-site debugging and verification.

2 REST API cycle polling (IT upper system)

The host periodically pulls and filters data in JSON format, which is lightweight and low bandwidth, suitable for timed equipment inspection and SCADA periodic reading.

3 TCP Socket continuous streaming upload (high-speed raw data)

The TCP client of the device actively connects for a long time, directly pushes the ADC raw sampling values without intermediate processing, without packet loss, and is suitable for high-speed acquisition of vibration spectra.

4 TCP Socket Passive Push (Event Triggered Reporting)

After reaching the threshold condition, the device actively establishes a TCP connection to push alarm data, without the need for continuous polling by the host, reducing network load.

Core configuration capability for DAQ acquisition tasks

1. Two collection modes

One Shot single interval collection: fixed-point sampling with a set millisecond cycle, suitable for low-speed state inspection

Stream based data collection: TCP continuously outputs high-speed raw data, interval parameter failure

2 types of hardware triggers

Support software triggering, digital DI external triggering, and analog level triggering; The triggering modes include: pre triggering, post triggering, delayed triggering, intermediate triggering (pre - and post buffering), threshold level triggering, and repeatable triggering. The maximum buffering capacity for a single task is 8k sampling points.

3-channel dynamic sampling weight allocation (Channel Gain Queue)

The global 250kS/s total bandwidth can be manually allocated to different channels, such as allocating more sampling resources to high-frequency vibration channels to achieve multi-channel differentiated sampling rates.

Four types of data output (single channel can output multiple types in parallel)

RawData: 16 bit ADC raw value; 2. Voltage: converted voltage/current engineering value; 3. FFT_PowerSpec: onboard FFT spectrum power; 4. Customization: User defined C/C++filtering algorithm (compile. so library upload and run)

Key points to distinguish from the same series
